Elec trolling motor questions

[CG]

I have a small 10ft flat bottom aluminum boat that my grandson and I use to fish. Its probably a little small but we only take it on small lakes that dont allow gas engine powered boats. We've been using oar power the last couple of years and its a little cumbersome. I had electric trolling motor on my Christmas list and surprise I got the exact one I wanted (heh). Now I need a battery and some sort of small charger.

Its a Minnkota 40lb thrust 36" shaft. The manual reads 42 AMP draw.
Im looking at lithium batteries because I like the lighter weight. Looking on Amazon they have plenty under 150 bucks, some under 100 bucks. Im looking at this one.

Any input on battery choice for a small trolling motor? Ive never owned a battery I need to keep charged so Im also looking for input on a decent priced charger?

The battery you selected on Amazon has a 50Ah rating.
So you can pull one amp at 12V for 50 hours.
Your draw will run this for a little over one hour.
Drawing a battery down this far isn't perfect, it but depends on the battery type/style.
This one claims to offer a greater depth of discharge.
You should be good with 640W of power (it's 53 amps @12V).
If you need to go longer, purchase another battery and double your range.

I went ahead and ordered the battery I linked to. I thought about ordering two like you mention, but I want to see how this works out. Just gotta make sure we bring the oars with us (just in case). I also ordered this NOCO charger. I have NOCO jump box and Ive had good luck with it.
